The health production function in South Asia: panel evidence on education, health expenditure, governance, and longevity.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study examines the association of education, government effectiveness, health expenditure, economic growth, and urbanization with life expectancy in South Asia within Grossman's health capital framework. Using annual panel data for seven South Asian countries-Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka-over 2000-2025, the analysis investigates both long-run and short-run relationships. The empirical strategy combines panel unit root tests, panel ARDL estimation, Driscoll-Kraay standard errors, PCSE, FGLS, System GMM, and bootstrap panel causality tests. The results indicate a stable long-run relationship among the variables. Education, measured by school enrollment and adult literacy, is positively and significantly associated with life expectancy. GDP per capita also shows a positive and significant association. Health expenditure has a positive but model-sensitive association, suggesting that the effectiveness of spending may matter more than its level alone. By contrast, government effectiveness and urbanization are significantly associated with life expectancy but with negative coefficients in the estimated models. Bootstrap causality results indicate dynamic links between life expectancy and several explanatory variables. Overall, the findings highlight the importance of education, inclusive growth, efficient health spending, and better-managed urban development in shaping longevity across South Asia.
